The Rules

Commenting

Don't dig up personal info. Posting anything that even looks like personal information gets you a ban and reported to the admins. Don't do it. Ever.

Be honest but have some tact. Don't be a dick. There is no need to be rude or offensive

Try to comment on people of your own sex once in a while. In general, guys get way fewer comments than gals, so try to share the love.

Don't send creepy messages to submitters or post creepy comments. This includes any references to coitus, however phrased, or any other sexual activity.
If you get any such private messages and would like to report the offender, you should message the mods of /r/reddit.com (the admins) with a link to the offending message--harassment is against the sitewide rules.

Submitting

If you're under 18, don't submit. You're too young for anything that could be said here to affect you positively. You're going to grow up, your looks are going to change.

Better photos get better feedback. The closer your photo simulates how an average person sees you on a daily basis, the better. Heavy makeup, awful lighting, closeups, and dumb faces all result in worse feedback.

Keep it SFW. No nudes, no visible gender attributes. If it's borderline (bikini, for instance), include a warning so people know what they're about to open.

Don't post pictures that aren't of you. That means none of your friend or significant other, because protecting folks' privacy is important. They need to post their own pictures. Keep other people out of pictures of you (crop or scribble them out), because it's confusing for commenters and because people should have a choice in whether their pictures are posted here.

Don't use this place as a hugbox. If you just want someone to make you feel better, try /r/mmfb and/or /r/toastme, which are both for exactly that purpose.

Don't post more than once a month, unless you've seriously done something different. Don't repost at all unless you've changed or got very little feedback the first time.

If you want to talk about the subreddit, message the mods, because odds are everyone's heard it before, and we're the only ones who are going to change anything anyway.

No joke threads. There's too many possible jokes, if we allowed them we'd be flooded with them. M16, M5, M1, F-16, F-18, F-20, F-22, F-35, have all already been made. If you think of a new one, pat yourself on the back for being clever, but don't post it.

Optional:

Edit your thread to remove the photos afterwards. Don't just delete the post, because that will leave the photos up. Delete the post after you have removed the photos. Keep in mind that even this doesn't mean your photos are still somewhere on the internet, or on someone else's computer now.

Voting

Don't upvote/downvote based on appearance. Upvote/downvote based on whether the person needs more responses. If the person has few responses, or you just think they need more than they have, upvote.

Guy here, no homo, but I want your sweater in the 4th picture. Haha. But seriously I do.. And as for my opinion, you are a good looking man. Messed up hair + Facial hair suits you well. Might have a big nose, but doesn't matter. Eyes + smile make you look like a confident man and you have a great style going for you. I won't rate, just giving my criticism which I hope you take well. :)
